Any water or screen wash run off may run past the wing beading into the joint. I replaced the screws on the other side a while back and those screws were more rusty compared to this hot exhaust side. Anyway no bubbling so far so far, fingers crossed this might prevent it smile

I am a little wary of aluminium screws! When i renewed the guttering on the house, I used ali screws on the down pipe clamps to prevent eventual rust marks staining down the wall. However, when I needed to remove them, the heads turned to powder and were devils to get out. Maybe salt air as we are only a couple of miles from the coast, though the Severn is more mud than salt!
